After months of speculation, Dell may finally be ready to officially disclose its latest notebook in the thin-and-light category.

According to Electronista, the new notebook may make its formal debut this coming Tuesday, May 24th. Rumored to be the XPS 15z, this laptop will be the successor to the failed Adamo line, which was discontinued earlier this year. The 15.6-inch XPS 15z would compete directly with the Apple MacBook Air at launch.

Speaking of MacBooks, the Dell ultraportable has gotten some flak on its design front as of late. Last week’s official teaser of the Dell notebook showed off some of its features, many of which very closely resemble that of the MacBook Pro design. These include the sleek aluminum frame, slot-loading DVD drive, battery indicator lights, and speaker grilles. Nonetheless, the chassis is still quite attractive and would definitely stand out against other Dell laptops.

While the XPS 15z will supposedly start at $999 and come with Sandy Bridge Core i5 and i7 options, we might have to wait until Tuesday before we receive any kind of confirmation as well as additional details.
